Hi guys,
quick question in regards to ceph -> rbd -> quotas per pool. I'd like to
set a quota with max_bytes of a pool so that I can limit the amount a
ceph client can use, like so:
ceph osd pool set-quota pool1 max_bytes $(( 1024 * 1024 * 100 * 5))
This is all working, e.g., if data gets written into the rbd mapped
device (e.g. /dev/rbd0 --> /mnt/rbd0) and the pool reaches its capacity
(full), it sets the ceph cluster health to WARN and notifies that the
pool is full and the write stopps. However, when the write operation on
the client stops it also hangs after that, e.g. the process can't be
killed and waits for the device to respond, e.g.
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 9226 0.0 0.0 5836 744 ? D 12:50 0:00 \_
dd if=/dev/zero of=/mnt/rbd3/file count=500 bs=1M
Increasing the quota of the pool helps recovering the cluster health but
the write is stuck forever on the client (needs to be rebooted to get
rid of the process).
Ideas?
Cheers,
Thomas
